Holland's Automated Manganese Refurbishment (HAMR) service includes pre-weld material removal using plasma cutting, rail grinding, and robotically controlled welding procedures to build back the damaged area of rail frogs and diamond inserts.This process provides improved welding results through lower heat input into the parent material, maintaining temperatures below 500 degrees. This refurbishment is higher quality, longer lasting and can be completed two to three times faster than the traditional repair welding process. This helps reduce costs and track maintenance time by eliminating the need for repetitive repairs.From a sustainability perspective, HAMR gives new life to frogs and diamond inserts rather than railroads replacing these components. A full refurbishment service includes Holland HAMR weld warranty.
